AMD Bulldozer Dual-Interlagos Benchmarks On Linux

Phoronix: AMD Bulldozer Dual-Interlagos Benchmarks On Linux

Lately we have been talking a lot about Intel's latest Sandy Bridge processors under Linux due to their very competitive performance and interesting graphics abilities, but on the AMD side there has not been too much to talk about. On the low-end there is the intriguing Fusion APUs, but on the high-end they don't have an answer to Sandy Bridge until delivering their new "Bulldozer" products closer to the summer. Fortunately, we have the first Linux scoop and performance benchmarks from engineering samples of their 16-core Interlagos server chip.

1 / 800 vs 1 / 256 = SB is more than 3 times more efficient.
OK, Bulldozer runs at 2GHz, SB runs @ 3.2GHz, let's take it into account.
1 / 800 / 2 vs 1 / 256 / 3.2 -> SB is still 2(!) times more efficient.
I guess we'll have to see the desktop version of Bulldozer to draw any conclusions. I doubt any existing computational test today can scale to 32 cores without some major performance loss.

you calculate wrong because: an 16 core bulldozer do only have 8 real-full-featured-cores.

the OS only count 32cores in this test because its much better to use this 16 cores as a 32core.

A Dell PowerEdge server that's packing four Intel Xeon X7550 CPUs that each have six-cores and Hyper Threading with a 2GHz base frequency with 2.4GHz Turbo Frequency and 18MB of L3 cache, is the current winner in that category as shown by doing this dynamic comparison.
